Feature Progress

Define function definition syntax
Implement AST nodes corresponding to that syntax
Decide if (and how) to support variadic arguments.
- VA_LIST is kinda bad, but understandable.
Implement parser rules for new AST nodes
Write tests for new parser rules

Feature description

A function declaration adds a function definition into the local scope. The main function is run after the program starts, and exiting main causes the program to shut down. Other functions will eventually be callable using a Function Call.

Example

fn main (arg1: Type1, arg2: Type2, arg3: Type3, [...]) -> ReturnType { 
    /* Expr | Empty */ 
}

I've decided to leave variadics off. As of right now, the perma-unstable builtin system allows them, but all native Conlang functions have a fixed number of arguments.
